The Microsoft Internet Explorer Weblog reported new improvements related to security and user experience for HTTPS connections. It is said that for Internet Explorer 7, the default HTTPS protocol settings will be changed to disable the weaker SSLv2 protocol and to enable the stronger TLSv1 protocol. On this way IE7 users will negotiate HTTPS connections using SSLv3 or TLSv1.
The blog says that Internet Explorer 7 users will not notice any difference in the user-experience due to this change as it’s a silent improvement in security. Microsoft’s research indicated that there are only a handful of sites left on the Internet that require SSLv2.
